Subject: [PATCH 1/2] net: spider_net: Fix the size used in a 'dma_free_coherent()' call
Date: Sun,  2 Aug 2020 15:53:33 +0200	[thread overview]
Message-ID: <20200802135333.690991-1-christophe.jaillet@wanadoo.fr> (raw)

Update the size used in 'dma_free_coherent()' in order to match the one
used in the corresponding 'dma_alloc_coherent()', in
'spider_net_init_chain()'.

Fixes: d4ed8f8d1fb7 ("Spidernet DMA coalescing")
Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

NOT compile tested, because I don't have the configuration for that
